Event overview

Events encapsulate communication between the viewers and the game process. From the website, you can decide which information the viewer can send into the MapReduce system which is then received in the game. Events are composed of a key:value pair.

We designed Genvid scalability around a MapReduce algorithm which filters the events and combines them into a limited number of outcomes. This drastically reduces both frequency and bandwidth impacts.

Note

Since 1.43.0, summaries can now be received directly by the viewers through the Notifications system, without going through the game.

The basic event flow is:

• Event Generation (typically issued by the viewer in JavaScript)
• Event Filtering (done using MapReduce inside the events service)
  • Map example
  • Reduce example
• Event Consumption (done by the game)
  • Subscription
  • During the execution
  • Event structure content
